A thermal power station
is a power plant
in which the prime mover is steam driven. Water is
heated, turns into steam and spins a steam turbine
which drives an electrical generator. After it passes
through the turbine, the steam is condensed
in a condenser and recycled to where it was heated;
this is known as a Rankine cycle. The greatest variation in the
design of thermal power stations is due to the different fuel sources. Some
prefer to use the term energy center because such facilities convert
forms of heat
energy
into electricity. Some thermal power plants also deliver heat energy for
industrial purposes, for district heating, or for desalination
of water as well as delivering electrical power. A large proportion of CO2
is produced by the worlds fossil fired thermal power plants; efforts to reduce
these outputs are various and widespread.
